All Implemented Interfaces:

java.io.Serializable
```
public class Data
 implements Serializable
                    
```
Use this class to store database-like data. This class uses rows and columns to organize its data. It has some convenience methods that allow fast loading and retrieval of the data into and out of string arrays. It is also handy for reading CSV files. WARNING: the class assumes that column names are unique, but does not enforce this.
